rlhis invention relates to a miners lamp, and particularly to a cleaner or scraper.

The invention aims to provide an iinproved scraper or cleaning device particularly adapted for use in the carbid chamber' of the lamp, for scraping or removing the particles of carbid from the wall of the chamber.

The invention further aims to provide an especially constructed scraper located in the carbid chamber, and means carried by the closure for the lower end of the chamber to engage the scraper, whereby, upon rotating the closure, the scraper is rotated in the he particles of carbid chamber, scraping t from the wail.

The .invention further aims to provide a scraper consisting of a pair of similarly constrncted skelet-on frames riveted or otherwise together and having means engaging about the water feed tube from the water chainbe to support the scraper concentricaiiy in thecerbid chamber.

rihe invention further aims to provide a caper, the two 'frames of which near their: ower ends being partialy separated, for the receptie i of a pair of uprights carried by and rising upwardy from the closure for the carbid chamber, so that when rotating the ciosure, the scraper Wiil be correspondingly rotated.

invention further aims 'to provide I having a chamber super-imlation to the carbid chan'ilz-cr,

aching, which cong or straining means for the i through the central opening t on. between the'two chambers,

gas emanati in the parti that is ascending from the carbid. It is to be noted that an advantage device isthat the threads connecting the two sections of the lamp never become corroded.

While the design and construction at present illustrated and set forth is deem l prefble it is obvious that a resuit of a 're- .i I s Y of the present,

tion may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

rEhe invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure l is a vertical sectional View through a ininers lamp, showing the upper and lower chambers, and illustrating the scraper as located in the carbid chamber.

Fig. 2 is a horizontal sectional view on line 2`2 o ig. l

Fig. 3 is an enlarged detail view of the scraper removed from the chamber.

ig. L is a detail view of the closure for the carbid chamber.

eferring more especially to the drawings which consists of two sections 2'and 3. The upper section is of the usual construction, and is provided. with a downwardly extending contracted threaded part 4, into which the threaded extension 5 of the lower section 3 is threaded. Extending from the bottom of the iipper section and in communication with the water chamber 2a of the upper section 2 is a water conducting tube 6, there being openings 7 adjacent the diametrically opposite sides of the tube adjoining the gas chamber 7a. The lower section 3 has ay partit-ion Tvall 8 having a central opening 9 through which the water conducting tube By means of this partition upper and lower chambers l0 and l are Caused to be formed. The upper chamber receives a suitable packing, such. as wool or the lite 12 through ch the gas arising from the carbid passes.

' scraper 13, which is of a chape to fit the contour of the chamber. This scraper is provided with shoulders le, to engage the annular shoulder i5 of the carbid chamber, so as to support the scraper whereby its upper portion. be nr. el se position to the under tace or the partition. This scraper consists oit a pair of correspondingly constructed trames 1G, which are skeleton form. These two frames have their opposite side portions riveted together as shown at 17. The upper and lower tiansverseportions of the trames have diametrically opposed semi-circular portions 18 engaging on diametrically op osite sides of the water conducting tu e, whereby the scraper is maintc ined concentrically in the chamber, so that the opposite side edges of the vertical parts o the scraper may be'positioned in close position to the cylindrical wall of the chamber. lt is obvious that when the scraper is rotated the opposite side edges of: the riveted parts of the scraper will contact with the wall of the chamber, thereby remove or scrape the particles ot 'the carbid from the wall. Referring to the horizontal sectional view, and also to the detail view of the scraper, it will be observed that the lower portions ot the frames of the scraper are separated, sufiiciently :tor the reception of the uprights i9, nich extend vertically from the bottom ot' the closure :20, which has threads 2l. to engage the threads of the extension of the section 3. lt is apparent that upon rotatingthe closure, when detaching the same from the extension of the lower section 3, rights engaging between the two frames of the' scraper will cause a revolublc movement to be imparted to the scraper'. The edges of the scraper will then contact with the wall of the carbid chamber and scrape the particles tlierelron'i. The edges et the upper parts of the trames ot the scraper will also contact with the under surface of the partition, for the purpose ot' removing the particles of carbid. rlhe shoulders of the scraper contacting with the annular` shoulder lof the carbid chamber, will likewise re- -move the particles et used carbid from. the annular shoulder.

The invention having been set `forth, what is claimed as new and useiiil is:

l. in a miners lamp, the combination with a casing` having upper and lower chambers, the former being in superimposed relation to the latter, of a partition wall between the two chambers and provided with a central opening, a water conducting tube extending from the water chamber of the lamp through said openingand into the lower chamber, a. scraper mounted in the lower chamber and engaging the water con* ducting tube, whereby -the scraper is mailitained concentrically in the lower chamber, a closure for the lower chamber, and means the upmeente carried by the closure engaging said scraper, for imparting motion thereto when 'the closure is rotated.

2. ln a miners lamp, the combination. with a casing having packing and carbid receiving chambers, the former being superimposed with relation to the latter, of a partition between the two chambers and provided with a central opening, a water conducting tube extending from and in communication with the water chamber of the lamp passing through said opening and into the carbid chamber, a lscraper in the carbid chamber and rotatably mounted upon the water conducting tube, said scraper comprising a pair of oppositely disposed skeleton frames riveted together, a closure 'for the carbid chamber, and means carried by the closure engaging between lthe two frames of the scraper, whereby when the closure is rotated, revoliible movement is imparted to the scraper.

3. in a miners lamp, the combination with a casing provided with a carbid chain- .ber in its lower portion, of a bottom closure for said chamber, a water conducting tube leading from the water chamber of the lamp into the carbid chamber, a scraper mounted in the chamber being mounted upon the water conducting tube whereby it is held concentrically in the tube, and means carried by the closure and engaging the scraper, whereby upon rotating the closure, revoluble movement is imparted to the scraper.

4. ln a miners lamp, the combination with a casingprovided with a carbid chamber in its lower portion, of a bottom closure for said chamber, a water conducting tube leading from the water chamber or' the lamp into the carbid chamber, a scraper mounted in the chamber being mounted upon the water conducting tube whereby it is held concentrically in the tube, said scraper comprising a pair el: oppositely arranged correspondingly constructed skeleton trames,1

means for riveting the frames together, the upper and lower parts oi, said -trames having` semi-circular parts engaging the water conducting tube, the lower parts of the frames being spaced and means carriedby the bottom closure engaging between the fra-mes to rotate the scraper, when the closure is retated.
